"Darning" with a sewing machine is a quick way to sew repairs without patches, planning, or much skill. It doesn't matter how rotten and worn away the cloth is to start out.
Make your stuff last forever. Save the planet.
My favorite Makassarese sarong had a big rip in the back. A sarong is a tube of cloth worn as a skirt by men and women in places where the weather is good and the food is tasty. Makassar is a city in Sulawesi, Indonesia.
When I wore this in Indonesia people assumed I was a Moslem scholar from Makassar because I had a beard, this sarong, and a long sleeve shirt. When they asked me about that I would lie and say "I'm from Canada" because at the time the U.S. was being run by madmen. We'd just invaded and bombed a bunch of countries. Usually the person would respond with something like "Is that in New York?".
Step 1: Rip Something
First we'll do something simple.
This sarong was getting weak from salt crystals from using it to change in and out of wetsuits.
The cloth is kind of thin but it's still there. Except for the big rip, which was getting too big for me to use anywhere I might want to have a political career.
This is a perfect candidate for zigzag darning.
